Allow ARC target to be configured with --with-cpu=<cpu-name>.
gas * config.in (TARGET_WITH_CPU): Undefine. * configure.ac: Add --with-cpu support, and define in config.h. * configure: Regenerate. * config/tc-arc.c: Use TARGET_WITH_CPU to select default CPU. * NEWS: Mention new configure option.

* Add assembly-time relaxation option for ARC cpus.
|
||||
|
||||
* Add --with-cpu=TYPE configure option for ARC gas. This allows the default
|
||||
cpu type to be adjusted at configure time.

* Add a configure option --enable-compressed-debug-sections={all,gas} to
